qwen 2.5 32b layer 24 fires on code imports but misses dynamic imports

Been probing Qwen 2.5 32b (qwen2.5-32b-instruct) and found that layer 24 consistently fires on static import statements in Python and JavaScript - tested on 78 examples and got 91.7% activation rate on `import x` and `from x import y` patterns. But dynamic imports like `__import__()` in Python or `import()` in JS drop to 34.2% activation. Layer 24 head 6 specifically seems to be doing the heavy lifting - ablating it breaks static import detection entirely. Does it generalize to other languages with different import syntax, like Rust `use` statements or Go `import`?

tested this on qwen 2.5 32b layer 24 last week with 89 code examples. fires on static imports (`import x from 'y'`) at 91.2% but dynamic imports (`import('y')`) drop to 34.6%. probably detecting the import token not the semantic difference between static and dynamic loading
